Bridge uniform-section solid double-column square pier rolling formwork system and construction method
The invention relates to a bridge uniform-section solid double-column square pier rolling formwork system and a construction method.The bridge uniform-section solid double-column square pier rolling formwork system comprises an enclosure truss, a connecting truss, a lifting frame, a lifting system and a rolling module, the rolling module is formed by sleeving a curled steel core mold with a PVC conveying belt, and a polytetrafluoroethylene film adheres to the surface of a curled steel formwork; end plates and bolt holes are only arranged at two ends of the steel core mold of the steel template to be connected with the lifting frame, the template truss platform is lifted through the wedge block type jack, and the rolling module surrounds the pier column to form a track device capable of walking along the surface of the pier column. The formwork system rolls and ascends, so that only binding steel bars and pouring concrete are left in pier column construction, and continuous operation and construction are not affected by the age of the concrete. Lifting of a uniform-section square pier formwork system and forming of a rolling walking device on the concrete surface are achieved, sliding friction of the formwork to the concrete surface is avoided, the concrete appearance can achieve the bare concrete effect, and high-quality, continuous and efficient construction of a bridge square column solid pier can be achieved.
本发明涉及一种桥梁等截面实心双柱方墩滚动模板系统及施工方法，包括围圈桁架、连接桁架、提升架、提升系统及滚动模块，所述滚动模块通过PVC输送带套于卷边钢制芯模上形成，卷边钢模板表面粘贴聚四氟乙烯薄膜，且钢模板钢制芯模仅在两个端头设置端板和螺栓孔与提升架连接，模板桁架平台通过锲块式千斤顶提升，滚动模块环抱墩柱形成可沿墩柱表面行走的履带装置。模板系统滚动上升使得墩柱施工仅剩绑扎钢筋和浇筑混凝土，且能连续作业施工不受混凝土龄期影响。本发明实现了等截面方墩模板系统的提升与混凝土表面形成滚动行走装置，避免了模板对混凝土面的滑动摩擦，混凝土外观可达到清水混凝土效果，可实现桥梁方柱实心墩的高质量连续高效施工。
